Question
If we don't destroy our planet, for how long it will be life on earth, and when is the end of our solar system? Will it go through a supernova and then into a blackhole?
There is no conceivable way we could destroy our planet. We might destroy our civilization with a nuclear war, or create a mass extinction from global warming and habitat destruction (not likely but a possibility), but the Earth would hardly be affected. Life will continue to evolve, and the Sun will continue its very slow increase in brightness for billions of years. When the Sun does finally use up the hydrogen in its core, it will expand into a red giant and destroy any life that might still exist. The Sun is too small to ever create a supernova or black hole. It will end its existence as an inconspicuous white dwarf star. You can learn more about the fate of the Sun by looking up topics in “stellar evolution”.
